Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169638, here are decompositions:

5 + 169633 = 169638
11 + 169627 = 169638
31 + 169607 = 169638
47 + 169591 = 169638
71 + 169567 = 169638
107 + 169531 = 169638
137 + 169501 = 169638
149 + 169489 = 169638

Showing the first eight; more decompositions exist.
